To all whom it may concern) 7 Be it known that I, BnNJ'AMi'N S. SPAUIF- me, a citizen of the United States, residing at Arcata, in the county of Humboldt and 5 State of California, have invented a new and useful Log Trolley, of which the following is a specification.

The device forming the subject matter of this invention is a trolley adapted to be used for logging operations and the like, the device being so constructed that the same will maintain its grip upon-the cableway whilst the log or other article is being drawn along the ground, the construction being such that when the log is out of engagement with the ground, tne trolley will move readily along the cableway;

This invention discloses a trolley opera ing after the manner of the structure shown 20 in my Patent No. 1,065,399, granted on June 2 1, 1913. and the present invention aims to.

accomplish the result contemplated in the patent above mentioned. through the instrumentality of a much simplified means. It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which th invention appertains. Y

With the above and other bjects in view, which will appear as the description proceeds. theinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention. In the accompanying drawings Figure 1 shows in longitudinal section, a device constructed in accordance with the invention, parts appearing in elevation; Figure 2 is a top plan, the line 1-1 in Figure 2 indicating the cutting plane on which Figure 1 is taken; Figure 3 is a section on the line 33 of Figure 1.

The trolley forming the subject matter of this invention includes a pair of side" Application filcd Oc tober 3, 1921. Serial'l loi 505,031..

spacers being located between the sidemembers orrplates 1. Clevices 7 are mounted on the connecting devices?) and serve as places j of attachment forv the outhaul and return lines.

Shafts 8 are journaled in theupper corners of the plates 1, sheaves 11 being journaled on the shafts 8 and being located be- 7 '65 Shafts 12 are mounted in the side plates 1, between the shafts 8 and are located at a tween the side members or plates 1.

tween the side plates 1. 7 All of the shafts hereinbefore enumerated, may be provided with bores 9, the outer ends of the shafts carrying oil cups 10 communicating with the bores. the obvious function of the Oll'CUPS and the bores being to lubricate the variousv sheaves.

A slide 17 preferably inthe form of a bar, isheld for right line sliding movement in the guide grooves 41. Intermediate its ends, the slide 17 is supplied with an opening 18.

' A pin or axle 19 is mounted in the slide 17' and extends across the opening 18. The ends of the pin or axle 19 are adapted to be received in the seats 3, to hold the slide against movement longitudinally of the plates when in lowered position. A sheave 26 is located in the opening 18 of the slide 7 I 17 and is carried for rotation on the pin or axle 19. In the lower end of the slide 17 there is a notch 20, across which extends a bolt 21. The upper ends of a clevis 22 are mounted on" the bolt 21. A block 24 is supported on the lower portion of the clevis 22 and has a reduced upper end 23, received in the notch 20 which is fashioned in the lower end of the slide v17, the parts above enumerated coacting to steady the block 24;. A

pulley 25 is journaled in theblock 24:.

What is claimed is i V -1. In adevice of the class described,,a

trolley, sheaves journaled in the upper portion of the trolley; a slide mounted for reciprocation in the trolley and located between the sheaves; a sheave carried by the slide; interengaging elements on the slide and on the trolley, limiting the movement of the slide; and a pulley block carried by the slide. 7 v

2. In a device of the class described, a

5 trolley; sheaves located in the upper and lower portions of the trolley; a slide carried by the trolley and mounted for right line reciprocation and located between the sheaves; means for limiting the reciproca- 10 tion of the slide; a guiding means carried by the lower end of the slide; and a sheave mounted on the slide.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.
